00 er 6 said indicator arm and plunger being latter receiving an abutment plate 25 and being secured to the latter by a nut 26. One end of the abutment plate is extended to provide the spring,

a finger 27, which is engaged by one end of a spring 28. The opposite end of said spring is anchored on a stud 29, which is mounted in a recess 30. formed in the upper face of the base portion 10 of the feeler frame.

in use of this device, the serrated end of the fin 'er is adapted to engage the yarn on the bobbin to thereby hold the slide in a forward position and correspondingly permit the actuator to operate. As soon, however, as the yarn has been removed from the bobbin, the serrated end 31 of the finger impinges against the smooth periphery of the bobbin thereby permitting the finger to flex against the resistance of the spring 19 and allowing the feeler slide to move rearwardly, which correspondingly moves the arm 6. T his movement urges the plunger 6 through the chopper or actuator to render the latter operative and permits the bobbin to deft in a manner well known in the art. it is well lrnown that with feeler or filling detectors now used, a certain amount of yarn remains on the bobbin with a consequent loss of material. it has been found, however, that the device of the present invention will not pert the bobbin to deft until after the yarn been completely eXhau tel from the bobbin with a very appreciable saving on each loom. it is possible to effect this result because of the delicate nature of the mechanism employed especially the particular conmounting the finger and the particular manner of mounting feeler slide 13. in addition, the springs 19 and 28 are almost completely housed to prevent oreign particles from in any way retarding their effectiveness. Furthermore the device is susceptible to quick adjustment when necessary.

Although I have above described the present preferred form of this invention together with a preferred method of use, it is nevertheless to be understood that various changes may be made therein, especially in the details of construction, prportion and arrangement of parts within the scope of the claim hereto appended.

I claim:

A feeler for looms including a frame engageablc with the loom and equipped with a feeler slide, a feeler finger pivotally mounted on one end of said slide and comprising a relatively long and narrow bar, the bobbin engaging end of which is remote from the slide and is equipped with serrations for engagement with the arm, the opposite end of said finger being enlarged with one side thereof obliquely disposed, a spring anchored on the slide one end of which impinges against said oblique side of the feeler finger, means to normally urge said slide and finger rearwardly toward the active bobbin, said being flexed, against the resistance of to permit the slide to be urged rearwardly for transferring the bobbins when the supply of yarn on the active bobbin is completely exhausted.

DAVID LEMIEUX.
